OIL BURNER.

Application filed November 22, 1923. Serial No. 676,342;

T 0 all to 710m it may concern Be it known that I, AARON Annowsrrrrrr, a citizen of the United States, residing at Sisseton, in the county of Roberts and State of South Dakota, have invented certain new and useful Improvements in Oil Burners; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make" and use the same. I

The invention relates to. oil burners and has for its primary object to provide a burnerfor ut-ilizingkerosene or like hydrocarbon as fuel, the burner being self-cleaning. by the pressure of gas generated when priming the burner preliminary to lighting the same, the construction being such as to insure a steady and even flame and to prevent the pressure forcing the oil from the fuel pipe back into the tank, and as a result it is possible to dispose the tank at a relatively low level so as to be conveniently filled.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodi ment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes inthe form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Referring to, the accompanying drawings forming a part'of the application 2 Figure 1 is an elevational view of an oil burner embodying the invention,

Figure 2 1s a plan view thereof, the fuel pipe and tank being omitted, and

Figure 3 is an enlarged sectional view of the generating burner, priming cup and a portion of the band or support.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates asuitable stand or support upon which is mounted two burners embodying the invention. This stand or support may be of any preferred construction, according to the adaptation of the invention.

The burner is of a nature to convert the fuel into gas, the latter escaping and burning at the outlet. The burner comprises a of the burners and is mately of 'T-forni,

shallow chamber which is comprised between a bottom 2 and a top 3, and provided with a centrallydisposed outlet 4 for the escape of the gas. The bottom 2 is depressed and slopes upwardly and joins the outer edges of the top 3, a space 5 being enclosed between. the bottom 2 and top 3 which constitutes the generating chamber in which the fuel is vaporized. A pipe 6 connects cent-rally withthe bottom 2 of the generating chamber and its upper end receives a valve 7. The pipe 6 leading from the burners connects with the'fuel pipe 8 and each is provided with a controlling valve 9 to regulate the supply of off the supply as required. The fuel pipe 8 connects with a tank 10 and the latter may be disposed slightly above the plane of the burners because of the provision of the valve 7 which operates as a check to prevent the pressure of gas generated in the chamber 5 from causing the return of the oil to the tank 10. A drip cup 11 is located below each designed to hold a fuel to admit quantity of A spreader 12 is 10- starting the burner. cated above each of line with the outlet 4: and serves to deflect or spread the flame when the burner is in operation. A suitable support 13 is provided for holding the spreader 12 in operative position. As shown, the support 13 is approxihowever, it is to be understood that its particular structure will depend upon the adaptation of the burner.

In practice, upon opening a valve 9, the fuel is admitted to the burner and after filling the chamber 5 escapes through the outlet 4: and trickles over the burner and drips into the cup 11 and after the latter has received a suitable supply, the fuel therein is li hted and the flame playing upon the burner heats the same and vaporizes the oil which is. forced through the outlet 4; in such a manner as to remove any matter tending to clog the same.

In the event of the pressure exceeding that causing the feed of fuel to the burner, it reacts on the valve 7 and causes the same to seat, thereby preventing any back pressure which wouldtend to return the oil from the fuel pipe to the tank. WVhen the pressure in the generating chamber 5 becomes slightly less than the pressure exerted by the feed of the fuel, the latter effects an unseating of the valve 7 and the burner is kept supplied with fuel or entirely out of priming or the burners directly in the latter being flat the result that the, flame is steady and uni-- form.

V hat is claimed is:

l. A burner device of the class described having a support, fuel supply pipes rising above said support, burners to which said pipes lead having casings attached to the pipes, valves within the easings: subject to the pressure of the fuel when seated directly on the upper ends of the pipes, stems on said valves depending into the pipes, the upper Walls of the casings serving to prevent: displacement of the valves, 11 substantially T- shaped braclffet rising from the support, spreaders carried by said bracket and arranged suhstai'ltially centrally with respect to and over the burners, and starter pans of greaterarea than the burners secured on the pipes intermediate the supportingplate and 30 burners.

2. A burner device of the class described having fuel supply pipe, a one-piece burner in hollow formation provided with an opening in its top and an opening in its bottom in alignment with the first mentioned opening, the bottom opening being larger than the top opening and fitting the upper end 01' said pipe for attachment to the latter, a valve insertahl'e through the bottom opening and being seated directly on the upper end of the pipe, said valve being subject to the pressure of the fuel, a stem on said valve dependinginto said pipe, and a starter pan of greater area than the burner disposed below the burner and secured to said pipe.
